. To Qua/idea Camera-i" I Be it known that we, FRANK S. BAIL ".D

UN TED. swe te er a ae v s b and GEORGE WVM.. BALLARD, citizens of th United States, residing'at Duii, in the county of Rock and State of Nebraska, have invented certain new and useful Improvements in Pump-Rod Couplings; and we do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to certain new and useful improvements in coupling devices for Wind mill and other pump rods, and has i for its object to provide a coupling which i may be quickly and easily connected or disconnected and which may also be economically produced.

With these ends in view, our invention consists in the details of construction and arrangement hereinafter particularly described.

In order that those skilled in the art to which our invention relates may know how to make and use the same andto fully appreciate its advantages, We will proceed to describe the construction and the manner of applying and disconnecting the same, referring by numerals to the accompanying drawings in whichz Figure 1 is a perspective view showing the coupling released from an ordinary pump sucker rod. Fig. 2 is a similar view showing the coupling device connected to the reciprocatory pump rod.

Similar reference numerals indicate like parts in both figures of the drawings.

1 represents the lower end of an ordinary pump wind mill rod and 2 a vertical reciprocatory pump rod adapted to be operated by a wind mill, or by a handle 3, in any suitable manner. a

Our improved coupling device .for con necting quickly and easily the mill rod 1 with the reciprocatory rod 2, consists of two metal bars 4-4 bent near their upper ex-' tremities as clearly shown to embrace the end of the mill rod to which they are at tached by an ordinary bolt 5. These bars are so bent that when attached to the mill rod they will contact a shortdistance from the lower extremity of the mill rod and constitute a fulcrum upon which the longer free ends may vibrate as springs when they are embraced and confined Within a slidable ring a 6. The lower end of one of these bars is a ass tems; "or burial Nnn per end of the reciprocatory rod 2, and secured to said bar a shortdistance above the bolt7 is a U-shaped brace 9, for the purpose presently explained. The other bar 4 is provided with a hole 10 adapted to register with the hole 8 in the end. of the rod 2 when the lower ends of both rods 4 are caused to embrace the upper extremity of said rod 2,

and at such time the bolt. 7 passes through the holes 8 and 10 and the brace 9 embraces the edges of the bars 4, 4 and rod 2 as clearly indicated at Fig. 2 While the ring 6 firmly holds the bars and rods in contact in an obvious manner. a

When it is desired to uncouple the rod 2 from the mill rod 1 it is only necessary to slide the ring 6 upward a sufficient distance to permit the bars 4, 4 to spring apart as clearly illustrated at Fig. 2, which action causes the bolt 7 to be withdrawn.

to prevent the separation of the ring from the bars 4, 4, and being located a suitable distance from the bolt 7, stifl'ens the con-.

secured to one of the bars 4, by rivets as shown,.or :it may be welded thereto, or secured 1n any other preferred manner.

It will, of course, be understood that the metal of which the bars are made should be of such character as to cause the lower ends toispring apart when the confining ring 6 is pushed toward the upper extreniitiesu The dimensions ofthe bars 4, 4 are to be such as may be desired.
